It's a cool program nonetheless. Well done!
Other 101/141 owners have reported success, so you may just be missing a step or the running into some of the display's quirks. First, make sure the display is receiving a video signal on the input when you adjust and save the ISFccc mode. Also, make sure you press the Save button and then the Exit button after making your adjustments, then power off/on.
I ran into a similar issue trying to enable ISF Night on my 500M during testing - I ended up getting either ISF Auto or Day activated first and then was able to activate ISF Night. I am not sure exactly what got it working other than persistance.
If you don't make any progress, you may want to consider purchasing ControlCal which has the benefit of additional picture controls (those you can see in the Pro Adjust menu in non-ISF mode) for a reasonable price.
